Patients who develop uveitis may do so as a result of infection, trauma, or autoimmune disease. Uveitis can be triggered by inflammation caused by pathogens such as bacteria, viruses, fungi, and parasites that invade eye tissues, and in some cases by inducing antigen-antibody and complement complex reactions. If the patient’s eye is damaged, such as trauma to the eye, such as localized eye surgery and more severe blunt contusion, it may cause pathogens to enter the eye, thus triggering the occurrence of uveitis. When the body’s immune function is disrupted, antigens in normal eye tissue are recognized by the immune system, resulting in an immune response that leads to the activation of immune cells and the release of cytokines, which can also lead to uveitis. It is recommended that patients with uveitis visit a hospital in a timely manner to have their condition evaluated and treated under the guidance of a physician.
